Use cautiously in:
• thrombocytopenia, coagulation disorders, established RSV infection.
☞ Keep epinephrine 1:1,000 available in case anaphylaxis occurs. (However, drug isn't known to cause anaphylaxis.)
• Dilute in sterile water for injection. Gently swirl for 30 seconds to avoid foaming.

Skin: rash, fungal dermatitis, eczema
Other: hernia, pain, fever, injection site reaction, viral infection, flulike symptoms, failure to thrive
Drug-diagnostic tests. Alanine aminotransferase, aspartate aminotransferase: increased levels
Hemoglobin: decreased level Immunological-based RSV diagnostic tests: interference, possibly leading to false-negative test results
☞ Watch closely for signs and symptoms of anaphylaxis immediately after dosing.
• Assess for signs and symptoms of infection, particularly EENT and respiratory infection.
• Monitor liver function tests and CBC.
• Assess patient's weight and hydration status.
